To improve the information utilization and accuracy in teaching, a Chinese and English text classification algorithm is proposed. The algorithm is based on an improved Chi-squared test feature selection (CHI) algorithm. The performance of CHI is optimized by adding parameters such as word frequency, document coverage, and coefficient of variation to the CHI algorithm. According to the experimental results, the proposed algorithm achieved a recall of up to 1.0 under the Chinese dataset. Its accuracy rate was 0.49 higher than traditional CHI. Under the English dataset, the MO of the proposed algorithm reached 0.9. The results indicate that the proposed algorithm has reliable classification ability for both English and Chinese texts and has the potential to be applied to the English language teaching cloud classroom.<\/jats:p>","DOI":"10.1515\/comp-2024-0007","type":"journal-article","created":{"date-parts":[[2024,7,12]],"date-time":"2024-07-12T15:40:46Z","timestamp":1720798846000},"source":"Crossref","is-referenced-by-count":1,"title":["Chinese and English text classification techniques incorporating CHI feature selection for ELT cloud classroom"],"prefix":"10.1515","volume":"14","author":[{"given":"Yufen","family":"Wei","sequence":"first","affiliation":[{"name":"School of Foreign Languages, Weinan Normal University , Weinan , 714099 , China"}]}],"member":"374","published-online":{"date-parts":[[2024,7,12]]},"reference":[{"key":"2024071215404284945_j_comp-2024-0007_ref_001","doi-asserted-by":"crossref","unstructured":"P.
